Transparent and Colorless Dye-Sensitized Solar Cells Exceeding 75% Average Visible Transmittance.

ABSTRACT: Most photovoltaic (PV) technologies are opaque to maximize visible light absorption. However, see-through solar cells open additional perspectives for PV integration. Looking beyond maximizing visible light harvesting, this work considers the human eye photopic response to optimize a selective near-infrared sensitizer based on a polymethine cyanine structure (VG20-C _x ) to render dye-sensitized solar cells (DSSCs) fully transparent and colorless. This peculiarity was achieved by conferring to the dye the ability to strongly and sharply absorb beyond 800 nm (S₀-S₁ transition) while rejecting the upper S₀-S _n contributions far in the blue where the human retina is poorly sensitive. When associated with an aggregation-free a
